Car running lean after 1.5.1 update
Posted: Sat Jun 25, 2011 3:43 pm
My car has ran flawless for the past 9 months until this morning when I updated to the newest 1.5.1 KManager. Prior to this update I believe I was running the 1.4.1 manager. The version I had did not have any of the new WOT comp tables or knock control stuff etc. Now this is what is happening
Idle - went from my normal 14:1 to 18:1 and leaner.
Cruising - below 3k rpms went from 14.5:1 to 16:1 and leaner
0" vac - remains untouched
Boost - AF's are the same but now car is breaking up horribly
The funny thing is that once in a while, the car will snap out of whatever "mode" its in and all AF's go back to normal but then shortly after, back to the extremely lean AF's. I have not touched one thing on this car and now it's running like crap after this update. I have rechecked fuel pressure, voltage, and all connections and nothing is wrong. 9 months problem free and now this, so I blame the software. I have uninstalled and re-installed the newest 1.5.1 software with no luck.
Where can I download the past 1.4.1 software? I think it was 1.4.1.2 but I'm not sure. Any insight on this would be greatly appreciated. Moderator, if you need my KAL then I'll email it to you but I'm not going to share it on here, sorry.
This is in a 2002 S2000 with AP2 motor running KPro that I purchased back in May 2010. Its a stock motor with turbo, ID1000's, Walbro in tank and Bosch inline running 100psi base pressure.
